Incident Analysis

CMC Technology Group was targeted by Bianlian ransomware, one of the most active ransomware groups in our database with 201 confirmed victims globally. The attack was disclosed on March 31, 2025, when CMC Technology Group appeared on the group's dark web leak site.

CMC Technology Group is based in Vietnam , operating in the Technology sector. Vietnam ranks #44 globally for ransomware attacks, with 45 victims in our database.

Sector context: Technology companies hold intellectual property, customer data, and source code β€” all highly valuable assets. A successful ransomware attack can also put downstream customers at risk through supply chain exposure.

Bianlian typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats β€” paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data.
